Proposal Title: Radar Imaging of Six Near­Earth Asteroids During April­September 2009
ABSTRACT:
We propose to use the Arecibo S­band radar to carry out Doppler­only spectroscopy and delay­Doppler imaging of
six near­Earth asteroids (NEAs) during April­September 2009. Two of these targets, (136617) 1994 CC and 2001
FE90, represent outstanding opportunities with peak signal­to­noise ratios of thousands per transmit/receive cycle.
The other four NEAs, 2008 SV11, (163697) 2003 EF54, 2005 CW25, and 2000 CO101, are weaker but still have the
potential to yield high­resolution 3­D shape models. Given detection statistics to date, it is likely that at least one
target will be a binary or contact binary system. It is also fairly likely that at least one high­polarization­ratio
target will be observed, enabling us to test the recent finding that such objects usually belong to the E or V
taxonomic classes.
